I've played a lot of escape games. This one is awful.
You link us to a Google Doc, which links us to another one. An escape game should be self-contained, not reliant on other sites.
The artwork on here is terrible. Cut-and-paste is rampant. It's pretty obvious where the items are just from how different they look from everything around them. The exception is the note with the Google Doc URL, which is hiding in the 4-square-pixel pocket of a tuxedo.
"Count all the doors and exit" is a pretty bad idea. Where, exactly, are we supposed to put in how many doors exist? The number of doors isn't the piano code, and there are no strings of numbers or letters anywhere in the game. The "code" is nowhere to be found. Unless we are to type entire URLs or stories into the piano, we have to force our way through - and since we have so many options and no idea how long the code is supposed to be, we are basically stuck. We can't just click on the door to leave after we go through the Google Docs.
The only slightly redeeming quality is the interactive piano.
Overall, bad art, bad design, and bad game.
